Question

您好我需要一些帮助来编写我的proguard-rules.pro文件。我对此知之甚少，到目前为止，在互联网的帮助下写了以下内容。

# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in C:\Users\Suresh Babu\AppData\Local\Android\sdk/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the proguardFiles
# directive in build.gradle.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#

以下是堆栈跟踪。当我启动我的应用程序时，它崩溃了。它应该打开一个闪屏和主要活动等。

使用outputs文件夹中的usage.txt文件和proguard-rules.pro文件中的-keep规则。这解决了我的问题。请遵循此github文档中的以下说明：https://github.com/futurice/android-best-practices

在此处添加部分文档，以防文档过时：

Proguard配置

ProGuard通常用于Android项目，以缩小和混淆打包的代码。

您是否使用ProGuard取决于您的项目配置。通常，您可以在构建版本apk时将gradle配置为使用ProGuard。

buildTypes {
    debug {
        minifyEnabled false
    }
    release {
        signingConfig signingConfigs.release
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

为了确定必须保留哪些代码以及可以丢弃或混淆哪些代码，您必须为代码指定一个或多个入口点。这些入口点通常是包含主要方法，applet，midlet，活动等的类.Android框架使用默认配置，可以从SDK_HOME / tools / proguard / proguard-android.txt中找到。使用上述配置，my-project / app / proguard-rules.pro中定义的自定义项目特定ProGuard规则将附加到默认配置。

与ProGuard相关的常见问题是，即使构建命令（即assembleRelease）成功而没有警告，应用程序也会在启动时遇到ClassNotFoundException或NoSuchFieldException或类似问题。这意味着两件事中的一件：

ProGuard删除了类，枚举，方法，字段或注释，考虑到它不是必需的。 ProGuard对类，枚举或字段名称进行了模糊处理（重命名），但它的原始名称间接使用，即通过Java反射。检查app / build / outputs / proguard / release / usage.txt以查看相关对象是否已被删除。检查app / build / outputs / proguard / release / mapping.txt以查看相关对象是否已被混淆。

为了防止ProGuard剥离所需的类或类成员，请为ProGuard配置添加保留选项：

-keep class com.futurice.project.MyClass {*; } 要防止ProGuard混淆类或类成员，请添加一个keepnames：

-keepnames class com.futurice.project.MyClass {*; } 有关示例，请查看此模板的ProGuard配置。阅读Proguard的更多信息。

在项目的早期，进行发布构建以检查ProGuard规则是否正确地保留了重要的内容。此外，无论何时包含新库，都要进行发布构建并在设备上测试apk。不要等到你的应用程序最终版本为“1.0”才能进行发布版本，你可能会遇到几个令人不快的意外，并且很短的时间来修复它们。

提示。保存您发布给用户的每个版本的mapping.txt文件。通过为每个发布版本保留mapping.txt文件的副本，可以确保在用户遇到错误并提交混淆的堆栈跟踪时可以调试问题。

DexGuard。如果您需要用于优化和特别模糊发布代码的硬核工具，请考虑DexGuard，这是由构建ProGuard的同一团队制作的商业软件。它还可以轻松拆分Dex文件以解决65k方法限制。

ProGuard正在摆脱一些必需的代码？
